How do I get over the countless failures? I’ve been chasing the $1,000,000 dream for years.
Well, you just don't need to go all in the next time you turn your profit into a huge one. The only one who can solve your problem is yourself but it doesn't just take overnight to get over with it, you need patience to yourself as well. I think you need a financial advisor if you still can't solve your problem, don't keep it all to yourself, the thing with those who have problems is that they know it but they aren't seeking help from anyone, especially an expert.
That is it, what I normally do is to take a break anytime I have a big win because that way is the only method to get out of the excitement of winning and wanting to go further on a higher wager stake that will increase the risk of losing at the end.
I had a very bad experience with one of the popular casinos we have in the forum when I won my first bet instead of quitting and taking a long break, I rather went in for multiple odds and increased the stake amount, and in the end, I lost everything including my first bet.
